I think the mix up is two fold

,
FIRST exiting/re-entering the country doesn't get you an "extension", it gets you a NEW entry stamp for 60 days just like the red one you got when you entered the country,
AND
you're not talking to any immigration person OR being taken to any immigration person when you border bounce π
You're contracting with a service to take you to the border, get you stamped out of thailand, get you stamped in and out of another country and stamp back IN to thailand to get a new entry stamp for 60 days.
if you applied for the METV online before you came here (as in you got an email of the PDF file that is your visa) PRINT it out as that is your actual visa and you show that with your passport when you stamp back into the country.
No matter what the company you're dealing with says, when you enter the country on a valid METV you WILL get stamped in for 60 days, and the officers at passport control when you stamp in know this
